Find LCM of 741,520,656,197 with Prime Factorization


2 741, 520, 656, 197
2 741, 260, 328, 197
2 741, 130, 164, 197
13 741, 65, 82, 197
57, 5, 82, 197

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 13 x 57 x 5 x 82 x 197 = 478804560

Therefore, the lowest common multiple of 741,520,656,197 is 478804560.

LCM Formula to Find Lowest Common Multiple of 741,520,656,197

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

741 x 520 x 656 x 197 = 49795674240

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

741 : 1, 3, 13, 19, 39, 57, 247, 741

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

197 : 1, 197

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,520,656,197, is 1.

Now, the common factors can be found like this.

741:3x 13x 19

520:2x 2x 2x 5x 13

656:2x 2x 2x 2x 41

197:197

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 13 = 104

Therefore, the value for common factors is 104.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 49795674240/(1x104)

LCM = 49795674240/104

LCM = 478804560

Thus, we can understand that the LCM of 741,520,656,197 is 478804560.
